5/8 * 4/5

= 1/8 * 4/1

= 1/4 * 2/1

1/2 * 1/1

Final answer = 1/2

<u>Answer
</u>

Option B) 7 is the correct answer

FD = 7cm

<u>Explanation
</u>

Here triangle AEC. D is the midpoint of EC and F is the midpoint of EA

So D and F be the midpoint of triangle AEC.

FD be the midpoint joining line.

We know that if any triangle, line joining the midpoint of two sides is the half of the third side.

Here the third side is 14cm, then FD = 14/2 = 7cm

So option B) is the correct answer.

2a^3 when a = 4:

**First, **to start out, our step should always be to substitute the value of the variable (a) into the problem. Below is what our new problem should look like with the value of the variable. Keep in mind that parentheses mean multiplication.

**Second, **our next step is to simplify 4^3. Four raised to the third power equals 64, so 4^3 = 64.

**Third, **this last step is quite easy. All you need to do is (2 times 64). Best to use a calculator on this or take the hard way and do long multiplication. Either way, the answer for 2 times 64 is 128.

Answer:
